| MSP 3402C Short Information MSP 3402C Sound Processor for Korea (68-Pin PLCC Package, 64-pin PSDIP Package, or 52-pin PSDIP Package) The MSP 3402C is designed as a single-chip sound processor for applications in analog and digital TV sets, satellite receivers, video recorders, and PC-cards for Korea. The MSP 3402C increases function integration in a spectacular way. The chips are produced in submicron CMOS technology and will offer a wide range of interesting features combined with high performance digital signal processing. The complete TV-sound-processing, starting at the Sound-IF domain, will be performed by one single IC. The IC's input signal consists of analog audio signals in baseband and at intercarrier position. The MSP 3402C covers the sound processing of the TV-standard M. The MSP 3402C is fully backwards compatible to the MSP 3410B/D, which include NICAM sound decoding. The MSP 3402C offers the following advantages: - two selectable analog inputs - Automatic Gain Control (AGC) for analog input: input range: 0.14 - 3 Vpp - Sound-IF frequency 4.5 MHz and 4.7242 MHz - integrated A/D converter - all demodulation and filtering is performed on chip and is individually programmable - no external filter hardware is required - only one crystal clock (18.432 MHz) is necessary - FM carrier mute function - flexible selection of audio sources - digital input and output interfaces via S-Bus for D2MAC, and via I2S-Bus for external DSP-Processors featuring Surround Sound etc. - digitally performed FM-identification decoding and dematrixing for Korea 2-tone system - digital baseband processing: volume, bass/treble or 5 band graphic equalizer, pseudostereo and basewidth enlargement - simplified controlling of volume, bass, treble etc. - increased audio bandwidth for FM-Audio-signals (20 Hz - 15 kHz, 1 dB) Sept/96 1 MSP 3402C Short Information S_DA_IN S_CL S_ID I2S_DA_OUT I2S_CL I2S_WS I2S_DA_IN_1/2 SBUS I2S Interface S1..4 I2S1/2L/R I2SL/R LOUDSPEAKER L LOUDSPEAKER R Sound IF ANA_IN1+ ANA_IN2+ Demodulator FM1 / AM FM2 D/A D/A DACM_L Loudspeaker DACM_R DFP Mono MONO_IN IDENT IDENT HEADPHONE L HEADPHONE R SCART_L D/A D/A DACA_L Headphone DACA_R SC1_IN_L SCART1 SC1_IN_R A/D A/D SC2_IN_L SCART2 SC2_IN_R SCART_R SCART_L SCART_R D/A D/A SC1_OUT_L SCART 1 SC1_OUT_R SC2_OUT_L SC3_IN_L SCART3 SC3_IN_R SCART Switching Facilities SCART 2 SC2_OUT_R Architecture of the MSP 3402C 33 34 39 MHz 5 9 MHz SAW Filter Tuner Sound IF Mixer Sound IF Filter Loudspeaker Vision Demodulator SCART Inputs AM Sound 2 2 2 MSP 3402C 2 2 Headphone SCART1 Composite Video SCART2 SCART3 SCART1 SCART2 SCART Outputs According to the mixing characteristics of the Sound-IF mixer, the Sound-IF filter may be omitted.
